摘要：

The path integral measure for a scalar field coupled to gravity in phase space is examined by constructing regulators for the jacobians, and explicitly computing Einstein, Weyl and other anomalies. The anomalies in phase space are independent of the choice of path integral variables ("the measure") and this shows that one can simultaneously satisfy the requirements of unitarity and absence of Einstein anomalies. For the corresponding configuration space measures we find that different measures give different anomalies, but these anomalies are all related to each other by local counterterms. © 1990.
